White light using Titan + PixInsight for stacking & wavelets

[NickK]

After mowing the lawn.. etc etc I had a few hours in the sun

This is my second attempt at solar imaging, setup as:

* Kendricks Solar film

* 105mm running at 1340mm fl (2x Powermate) - I really need a helical focuser as one speed is an interesting experience!

* Baader UV/UR cut + Neodymium 1.25" filters on the titan's nose.

169 images (0.000001 second exposures), stacked using PixInsight's star registration with inverse enabled then stacked using standard PI integration. After stacking, using ATrousWaveletTransform (small scale 32 scaling function) with the individual layers adjusted using live preview.

I hope you like it - as I said it's my second attempt and first attempt using PI todo the stacking. It seems that Registax and I don't get on...

Good work NickK.

Registax is a beast to use but worth it in the end. What were you not getting on with?

Playing around with the processing in PI.

In order of processing:

1. Created two masks that are inverses of the same image

2. Used Convert to RGB on the main image

3. Added the masks as alpha channels for the two images.

4. Used separate RGB/L to bring out detail in each image. Mottling in one, spot detail in the other - different colours.

5. Used pixel maths (simple as "imageA+imageB"!) to recombine the two alpha channeled images.

6. used "make image" from the preview to make a crop of the main spot.

7. Upsized to 600 x pixels .. saved png and uploaded here

Nice one! I too have the Titan and find it excellent for white light solar.
